Garmin 301 Custom position and heartrate (garmin301)

This format can...

read and write tracks

This format is derived from the xcsv
format, so it has all of the same options as that format.

This is a very simple format that
is most useful for exporting data from units that support heart rate
data such as
Garmin Forerunner 301™,
Garmin Forerunner 305™, and
Garmin Edge 305™, and
to other programs
for analysis. It's a simple comma delimited format that includes the
timestamp, 3D position information and heart rate so you can pull it
into a spreadsheet or graphing program.
